FOLDING ANCHOR.

SPECIFICATION forming part of Letters Patent No. 652,162, dated June 19,190D.

Application tied May 2,1900. seria No. 15,248. (No model.)

T0 all whom, it may concern: l

Be it known that I, GEORGE W. BLACKBURN, a citizen of the United States,residing at Sarasota, in the county of Manatee and State of Florida,have invented a new and useful Folding Anchor, of which the following isaspect' lication.

This invention relates to anchors, and has for its object to provide animproved foldable device of this character in Whichthe flukearms and theopposite stock-sections may be compactly folded against the shank of theanchor, so that the latter may take up but a very small space, and thusmay be conveniently stowed away in a small boat, while at the same timethe foldable parts are arranged to be conveniently unfolded and securedin their operative positions, so that the anchor may be quickly broughtinto readiness for casting overboard. It is furthermore designed toprovide for connecting the anchor chain or cable with one of the movableparts of the anchor, so that the strain upon the chain or cable willtend to lock some of the movable parts, and thus effectually prevent thesame from becoming folded,and thereby useless, While the anchor is -inuse to secure a boat.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion,

size, and minor details maybe made wit-hinA the scope of the claimswithout departing from the spirit or sacrificing any of the advantagesof the invention.

In the drawings, Figure 1 is a perspective view of a foldable anchorconstructed in accordance with the present invention and shown in itsset-up position in readiness for use. Fig. 2 is a side elevation of theanchor in its folded position and looking at one of the fluke-arms. Fig.3 is a similar view at right angles to Fig. 2.

Corresponding parts in the figures of the drawings are designated bylike characters of reference.

Referring to the accompanying drawings, l designates the straight shankcommon to all anchors, the lower end of which is flattened or laterallyenlarged and bifurcated longitudinally, so as to form the opposite earsimmediately above the arms is a sleeve or collar 7, to opposite sides ofwhich are pivotally connected the links 8, which have their outer freeends pivotally connected to the upper sidesofl the respective arms andsubstantially midway of their lengths. By this arrangement the slide orsleeve may be moved upon the shank to fold and unfold the arms, asclearly illustrated in Figs. 2 and`3. The outward swing or movement ofthe fluke-arms is limited by reason of the hinged ends thereof abutting,and the downward movement of the slide is limited by means of theopposite stop-shoulders 9, that project outwardly from the shank atpoints adjacent to the lower end thereof.

The stock comprises the opposite substantially short and fixed sections10, which are preferably formed integral with the upper end of theshank, and the outer movable sections 1l, which have their inner endspivotally or hingedly connected, as at 12, to the outer ends of therespective fixed sections, so as to fold downwardly and longitudinallyagainst the shank. The stock and nuke-arms being at right angles to eachother, as usual, do not interfere in the folded positions thereof.

Longitudinally slidable upon the shank and between the sleeve 7 and thestock is another slide or sleeve 13, which is provided with a yoke orlink 14., that slidably embraces opposite sides of the shank andnormally projects outwardly beyond the upper end thereof and is providedat its outer end with a ring 15 for connection with the anchor chain orcable 16. Pivotally connected to opposite sides of this latter slide orsleeve is a pair of links 17, which have their free outer ends pivotallyconnected IOO to the under or inner sides of the respective foldablestock-sections, so that the latter may be adjusted or folded by aslidable movement of the sleeve. It will be observed that the link 14 islocated in a plane at substantially right angles to that of the stock,so as not to interfere with the latter.

To hold the sections of the stock in their set-up positions, there isprovided a link or ring 18, which slidably embraces one of thestock-sectionsand is designed to embrace the inner end of the adjacentlink 17, as shown in Fig.1, whereby the slide 13 and the stocksectionsare held against relative movement and are thus locked in position. Theslidable ring 18 is provided with a reduced or contracted extension 19,which is designed to embrace the adjacent liXed stock-section l0 toprevent the stock from being accidentally folded when the anchor hasbeen set up for use.` It will be understood that the ring 18 is firstinverted, so that it may be passed by the enlarged pivotal connectionsof the fold= able stock-section and the adjacent link 17, afterwhich itis turned upon the smaller fixed stocksection in order that the reducedportion of the ring may embrace the fixed stocksection.

From the foregoing description it will be seen that the presentinvention provides an exceedingly durable and simple foldable anchor inwhich all of the parts are connected so as to prevent separation andloss thereof, and they are arranged for conveniently and quickly beingset up to place the anchor in proper shape for casting overboard. Alsothe strain of the anchor chain or cable is placed upon the slide 13, sothat the latter is always drawn tightly against the links 17, therebypreventing the stock-sections from becoming accidentally folded whilethe anchor is in use, and the link 18 holds the stock in position untilthe ilukes take holdupon the bottom. Moreover, the strain upon thefluke-arms is outward, and thus the latter are held against becomingfolded.

What is claimed is-l 1. Afoldable anchor, havinga sl1ank,which isbifurcated at its lower end, opposite arms, having their inner endsmitered to abut and pivotally mounted within the bifurcation of theshank, ukes at the outer free ends of the arms, a slide mounted upon theshank, links pivotally connecting the slide to the respective arms, anda stop provided upon the shank to limit the movement of the slide towardthe arms.

2. A foldable' anchor, having a shank, a foldable stock, and a slidemounted upon the shank, having a locking engagement with the stock, andalso provided with means for connection with an anchor chain or cable tohold the slide in engagement with the stock.

3. A foldable anchor, having a shank, opposite stock-sections pivotallyor-hingedly connected to the shank, a slide mounted upon the shank,links pivotally connecting the slide to the respective stock-sections,and means for connecting the slide to an anchor-cable.

4. A foldable anchor, having a shank, opposite stock-sections pivotallyor hingedly connected to the shank, a sleeve slidable upon the shank,links pivotally connecting the sleeve to the stock-section, and a yokecon nected to the sleeve, slidably embracing and projecting beyond theadjacent end of the shank, and constructed for connection with ananchor-cable.

5. A foldable anchor, having a shank, opposite stock-sections pivotallyor hingedly connected thereto, links pivoted to the re spectivestock-sections, and having a slidable connection with the shank, andalink or ring slidable upon one of the stock-sections and to embrace thelatter and the adjacent link, in the set-up position of the parts.

6. A foldable anchor, having a shank, opposite fixed stock-sections,foldable stocksections pivotally or hingedly connected to the respectivefixed sections, links pivotally connected to the respective foldablesections and having a slidable connection with the shank, and a link orring, which is slidable upon one of the foldable sections and arrangedto embrace the latter and the adjacent link, and also having a reducedlateral extension to embrace the fixed stock-section.

In testimony that I claim the foregoing as my own I have hereto ali'ixedmy signature in the presence of two witnesses.

GEORGE W. BLACKBURN.
